Seventeen samples from 17 patients with PA: 8 patients were classified as long-term survival patients (>3 years), while the 9 others had a short-term survival (<1 year). There was no significant difference in terms of T stage (p = 0.453), N+ status (p = 0.2), differentiation (p = 0.481), CA 19-9 (p = 0.236), or CEA (p = 0.322). There was a significantly larger resection margin in long-term survivors (2.13 mm vs 0.78 mm; p = 0.018). LongS long-term survival patients, ShortS short-term survival patients, CEA carcinoembryonic antigen, NA not available, CA 19-9 carbohydrate antigen 19-9. T and N describing the tumor/node/metastasis: T tumor, N lymph nodes; LNR lymph node ratio, Differ differentiation, W well-differentiated, P poorly differentiated, M moderately differentiated, Coll colloid, Vasc invas vascular invasion, G grading
